' SPECIFICATION forming part of Letters Patent No. 293,605, dated February 12, 1884.

I Application filedApi-il 5, 1883. (No model.)

T albwhom it may concern: Be it known that I, ALWILL URB-AHN, of Paterson, in the county of Passaic and State of New Jersey, have invented an Improved Machine for Making Ornamental Looped 00rd, of which the following is a specification.

, Figure 1 is a side elevation of my new machine for making ornamental looped cord. Fig. 2 is an end elevation of the same. Fig. 3 is a detail face view of the studded wheel used in the machine Fig. 4, a detail face view of the cord produced on the-machine. Fig. 5 is aplan ortop view of the n1achine.

Figs. 6', 7 8, and 9 are detail views, showing parts of the machine, hereinafter more fully referred to. 1 This invention comprises certain improvements in the machine for making ornamental looped cord which is described in Letters Patent of the United States granted to me October 31, 1882, No. 266,928. 1 The object of the present invention is,.principally, so to. improve the machine described in said patent that it will make the ornamental looped cord in alternate thicker and thinner sections of regular and uniform lengths, or of unequal lengths. Another object is to facilitate the introduction of the core-threads into the machine. The invention consists, first, in providing the aforesaid machine with a drawing or stretching lever, which at proper intervals is, by mechanism connected with the machine, moved to bear against and tighten .the cord, thereby producing, for the time being, a portion of the cord of reduced thickness, while, when afterward the strain ofthe lever upon the cord is removed,the cord will be produced of its normal or greatest thickness.

The invention also consists in forming on the taperingrod which holds the core-threads apart a perforated plate through which said coreethreads pass, and which can be taken out of the guide-tube, together with said rod, all as hereinafter more fully described; also, in means of adjusting said rod.

In the accompanying drawings, the letter A represents suitable frame-work, on whichthe machine is supported. 0 is the driving-shaft,

5o hung in the frame B of the machine, and carrying a driving-pulley, e, to which rotary motion is imparted by suitable belt or otherwise. The pnlley e connects by a belt, f, with another pulley, 9, that revolves around the tube h, which is fixed in the frame of the ma 5 5 chine. Another tube, 2, is fixed in the frame of the machine in line' with the'tube h, and both tubes are near to each other, as indicated I in Figs. 1 and 5, and as fully described in the aforementioned Letters Patent. Around the tube '1; is placed the revolving pulley j,which, by belt 7c, connects with the driving-pulley e. Behind the tube It is. supported on the frame B a platform, m, which carries a series of posts which are receptacles for the spools of the core-threads (1. These threads a are from the said spools carried through the tube h, whichat or near its inner end is partly closed by a notched or perforated disk, n. This disk at, as

described in the above-mentioned Letters Patcut, was securely fixed in the tube h, which made it quite difficult to pass the threads at through its apertures. According to one part of my. present invention ,1 fasten said disk or platento 7 5 l the rod H, which extends through the tube h, and projects beyond the same with its pointed end, so as to constitute a core-thread spreader,

as described in the above-mentioned Letters Patent. Figs. 6 and 7 show clearly the rod or wire H with its pointed core-spreading end, and provided with the enlargement or perforated disk n, which is intimately connected therewith. Figs. 8 and 9 show a different form of perforated dish a attached to said wire H. Whenever the wire H is withdrawn, together with the disk at, from the tube h, it will be quite easy to thread. itthat is to say, to put the threads at through the apertures ofthe disk nand then when the wire H is reinserted. 0 with the disknin its proper place,the disknwill constitute a guide'for the threads a, the same as though it was rigidly fastened in the tube h itself, as described in above-mentioned patcut. The rear end of the wire H passes through a tubular screw, T, which is supported by a post, U, that projects from the platform m. The end of the screw T bears against a bend or shoulder, a on the rod or wire H. When or spindles E, of which four are shown, and 65 i the wire H is in the machine, and if it should too be found that the cord comes out too large as to its diameter, it is only necessary to turn the screw T so as to move the wire H farther back and withdraw the thicker part of its tapering end from the convolutions of the enveloping-threads b and binding-threads c.

The pulley g carries a frame, F, in which are hung one, two, or more spools, G, that contain the enveloping thread Z), which is wound around the core-threads a at or about the place where the same pass over the pointed portion of the rod H. The pulley j carries a frame,L,in whichare hung spools J ,that carry the binding-threads c, by which the enveloping-thread b is tied to the core-threads, all as described in my abovementioned Letters Patent. The eord,finally issuing through thetube 1', passes round the friction-roller 0, (see Fig. 1,) and thence round the roller or drum M and around the pressing-roller N, the latter being hung in a lever, O, which is connected with a powerful spring, (I, so as to hold the roller N against the drum M and cause the finished cord to be fed through the machine with the proper speed.

The drum M is loosely hung upon the drivingshaft C of the machine, upon which driving-shaft is also loosely fitted a large toothed wheel, P. The same driving-shaft also carries a toothed pinion, T, which is rigidly fixed to said shaft. The pinion r meshesinto the teeth of a large gear-wheel, s, which is hung on a spindle, t, and which carries a pinion, u, that meshes into said loose wheel P. The loose wheel P, being thus driven at greatly re duced speed, as compared with the speed of the shaft 0, has a projecting pin or clutch, 12, (see Fig. 3,) that engages with the drum M,

so that the drum M receives its slow rotation from the wheel P. The cord, as it issues from the tube 2', and after having passed over the friction-roller 0, and before it reaches the drum M, passes through a loop, 10, that is attached to a lever, B, which is loosely fitted upon the spindle t, or upon any other suitable pivotal support, and which lever B has a toe or lower projecting portion, :0, that overlaps the face of the toothed wheel P, and is in the way of one or more pins or studs, 3 that project at suitable intervals from the face of the wheel P. Now, the wheel P being revolved in the direction of the arrow shown next to it in Fig. 2, will at the proper time bring one of its pins y against the toe 0c of the will be drawn closer together by the tension produced by said loop 10, and the envelopingthreads Z) will be wound upon the closer corethreads, and so will the binding-threads 0, thus producing, while the cord is under the stretching action of the lever B and its loop, a contracted part of the cord. In fact, if the cord were always under the stretching action of the lever B, it would be altogether as contracted as it now appears at certain intervals in Fig. 4. After the pin y of the wheel P has left the toe of the lever B, the strain produced by said lever upon the cord is at once terminated, and the fabric comes out again through the tube i at the proper maximum thickness, until again the lever is moved by a pin on the wheel P and the cord again stretched, the final effect being that indicated in Fig. 4- namely, a cord having alternate contracted portions 2- and expanded or enlarged portions 3. The lever B, instead of having a loop, 10, through which the cord passes, may simply have a projecting pin or stud which bears against the cord, stretching it when the lever is in the position shown in Fig. 2. There may also, if desired, be a lower guideloop, w on the lower extremity of the lever R, as shown; but this loop I do not deem es- Sential.

Instead of so arranging the machine that the contracted parts of the looped cord appear at regulari. 0., equalintervals, it may be so arranged by properly setting the pins y as to produce the contractions at apparently irregulari. 0., unequalintervals.

I olaini 1. The combination, with the guide-tube h, for the core-threads, of the inner rod or corepin, H, carrying the perforated enlargement or disk 12, which can be removed with said rod H, substantially as and for the purpose specified.

2. The combination of tlieposts E, tubes h i, core-pin H, and means for revolving spools containing enveloping and binding threads around the core-pin, with the lever it, having guide-loop 10, wheel P, having projection 7 rollers M and N, and means, substantially as described, for rotating the wheel P and roller M, all as and for the purpose specified.

3. The wire or rod H, having tapering front end, combined with the adj usting-screw T and post U, and with mechanism, substantially as described, for supplying the core-threads and wrapping the same with enveloping-threads and binding-threads, as set forth.
